Summary 

The performance of our SZ-M series , SZ series 10kV and 35kV load-ratio voltage transformer conform to the standard of GB 1094 "Power Transformer " and GB/T6451-2008 "Technical Parameter and requirements of Three-phase Oil-immersed Power Transformer". The iron core is made of quality cold –rolled silicon steel sheet ,and in full-miter non- puncture structure. The coil is made of quality oxygen-free copper, featuring good outlook and safe running . The products are widely used in power transmission and distribution of industrial and agricultural power networks.


Reliable Structure

Load-ratio voltage regulation , high reliability, advanced level of performance, reasonable economical indicators.The core joints are of stepped shape with 3 steps , and the surface of this core is coated with cured paint to lower losses and noise.
?The winding has novel structure and its oil passage is reasonable designed . Its newly designed insulation structure helps enhance its mechanical strength and the short circuit withstanding ability.?The oil tank is in two types –fully enclosed type and the type fitted with an oil conservator.

Excellent Materials

Oxygen-free copper lines of lower resistivity, which will become smoother and burr-free after series of additional surface treatment, so the load loss of our transformer is lower and the electric performance is better.
High-quality silicon-steel plates which are of lower unit loss, and the no-load of the transformers is lower.
High-quality wooden laminating insulation pieces, which won't split or move even under the influence of short circuit.Thoroughly filtrated transformer oil containing less water, gas and impurities, which makes our transformers work better.High-quality rubber sealing material, which can prevent the transformers form aging or leakage.
